Use the Quadratic Formula and a calculator to find all real

Use the Quadratic Formula and a calculator to find all real solutions, rounded to three decimals. (Enter your answers as a comma-separated list. If there is no real solution, enter NO REAL SOLUTION.)

x2 0.017x 0.069 = 0

solve for x

Solution

x2 0.017x 0.069 = 0

Quadratic root formula for ax^2 +bx +c =0

is x = (-b +/ - sqrt(b^2 -4ac) /2a

So, x = (0.017 +/- sqrt( 0.017^2 +4*0.069)/2

x = 0.271 , -0.254
